Can you produce an apitrace?

I will try tomorrow.

--- Comment #8 from Nicolai Hähnle nhaehnle@gmail.com --- Thanks, I can reproduce this on Polaris. No idea what's causing yet, though it seems there are actually some piglit tests affected by tesselation bugs as well (notably, arb_shader_image_load_store-coherency).

I can't reproduce this on Tonga and Polaris11. It seems to be fixed. Can you please confirm?

I can't reproduce the issue as well. It was still there just a few weeks ago.

I will do a more thorough check later today and close this issue if the problem is no longer there.
